A former diner, this restaurant is known for its hot bar scene. A great place to sip spirits (try the chocolate martini) and people-watch through the large front windows. The small plates are also good, especially the pad thai and the seared tuna. Open Monday-Thursday from 5 pm, Friday-Sunday from 10:30 am. 138 Market St. (off Second Street), Philadelphia.
